Abstract A method of repairing a guide vane part such as used in a turbine or a compressor, and having a series of peripheral openings defined by a series of guide vanes extending between two axially spaced housing portions. The method includes cutting the housing into two pieces along a radial plane extending through the junctions of the ends of the vanes with one housing portion, discarding the other housing portion, and providing a replacement housing portion with vanes and with at least some of the vanes having extensions. A series of apertures as provided in the remaining housing portion corresponding in size and position to the vane extensions, and the vane extensions are inserted into the apertures in the remaining housing portion from one side thereof to cause the free ends of the vane extensions to project through the apertures on the opposite side of the remaining housing portion. The projecting ends of the vane extensions are then secured to the remaining housing portion.
